LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and work-
manship under normal use and service. The warranty period is one year and
begins on the date of shipment. Parts, product repairs, and services are war-
ranted for 90 days. This warranty extends only to the original buyer or end-user
customer of a Fluke authorized reseller, and does not apply to fuses, disposa-
ble batteries, or to any product which, in Fluke's opinion, has been misused,
altered, neglected, contaminated, or damaged by accident or abnormal condi-
tions of operation or handling. Fluke warrants that software will operate sub-
stantially in accordance with its functional specifications for 90 days and that it
has been properly recorded on non-defective media. Fluke does not warrant
that software will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused prod-
ucts to end-user customers only but have no authority to extend a greater or
different warranty on behalf of Fluke. Warranty support is available only if prod-
uct is purchased through a Fluke authorized sales outlet or Buyer has paid the
applicable international price. Fluke reserves the right to invoice Buyer for im-
portation costs of repair/replacement parts when product purchased in one
country is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the pur-
chase price, free of charge repair, or replacement of a defective product which
is returned to a Fluke authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service cen-
ter to obtain return authorization information, then send the product to that ser-
vice center, with a description of the difficulty, postage and insurance prepaid
(FOB Destination). Fluke assumes no risk for damage in transit. Following war-
ranty repair, the product will be returned to Buyer, transportation prepaid (FOB
Destination). If Fluke determines that failure was caused by neglect, misuse,
contamination, alteration, accident, or abnormal condition of operation or han-
dling, including overvoltage failures caused by use outside the product’s speci-
fied rating, or normal wear and tear of mechanical components, Fluke will pro-
vide an estimate of repair costs and obtain authorization before commencing
the work. Following repair, the product will be returned to the Buyer transporta-
tion prepaid and the Buyer will be billed for the repair and return transportation
charges (FOB Shipping Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN
LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING

LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY
CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied
warranty, or exclusion or limitation of incidental or consequential damages, the
limitations and exclusions of this warranty may not apply to every buyer. If any
provision of this Warranty is held invalid or unenforceable by a court or other
decision-maker of competent jurisdiction, such holding will not affect the validity
or enforceability of any other provision.

Fluke i1000s
AC Current Probe
Introduction
The Fluke i1000s is a clamp-on ac current probe designed to expand
oscilloscope applications in industrial and power environments. The Current
Probe (shown in Figure 1) provides the following features:
• Ideal for measuring distorted current waveforms and harmonics.
• Allows accurate measurement of currents from 100 mA to 1000 A rms,
5 Hz to 100 kHz without breaking into the circuit.
• A passive filter eliminates noise and ring on rapidly rising di/dt wave-
form, ensuring accurate screen displays.
• Connects directly to an oscilloscope through a reinforced coaxial cable
and an insulated BNC connector.
• Rated for 600 V ac circuits of Measurement Category III,
Pollution Degree 2. (See "Safety Information" for definitions.)
Warning
Read "Safety Information" before using the probe.

Safety Information
Read the following safety information carefully before attempting to operate or
service the Current Probe.
In this manual, a
Warning identifies conditions and actions that pose
hazard(s) to the user. A Caution identifies conditions and actions that may
damage the Current Probe. International electrical symbols used are explained
in Table 1.

Warning
• To avoid injury and ensure safe operation of the probe,
follow all safety precautions detailed in this manual.
• Never use the probe on circuits rated higher than 600 V
in measurement category III (CAT III). Use extreme
caution when clamping around uninsulated conductors
or bus bars.
• CAT III equipment is designed to protect against
transients in equipment in fixed equipment
installations, such as distribution panels, feeders and
short branch circuits, and lighting systems in large
buildings.
• Do not hold the clamp anywhere beyond the tactile
barrier. See Figure 1.
• Adhere to local and national safety codes. Individual
protective equipment must be used to prevent shock
and arc blast injury where hazardous live conductors
are exposed.
• Use caution when working with voltages above 60 V
dc, 30 V ac rms or 42 V ac peak. Such voltages pose a
shock hazard.
• Check the magnetic mating surfaces of the probe jaws;
these should be free of dirt, dust, rust, or other foreign
matter.
• Do not use a probe which is cracked, damaged, or has
a defective cable. Such probes should be made
inoperative by taping the clamp shut to prevent
operation.
• Do not alter the Product and use only as specified, or
the protection supplied by the Product can be
compromised.

Operation
11
Operation
Use the following procedure to make a measurement:
1. Connect the i1000s Current Probe to the desired input channel on the
oscilloscope.
2. On the Current Probe, select the least sensitive range (1 mV/A). See
Figure 1 for selector switch location.
3. On your oscilloscope, select an appropriate range. Use a 1:1 probe setting.
Note
If using the Fluke ScopeMeter 123, use this procedure for step 3:
1. Press
(shown in Figure 3).
2. When the MEASUREMENTS screen appears, select AMP…
and ENTER.
3. When ENTER is pressed, the AMPERE PROBE screen
appears.
4. Select the appropriate range (i.e. 1 mV/A).
4. Clamp the probe around the conductor to be measured, and observe the
current waveform on your oscilloscope display.
Note
If using the Fluke 123 ScopeMeter, disregard the next step.
5. Calculate the Amps-per-division on your oscilloscope by dividing the
vertical scale (mV or V per division) by the i1000s switch position
(1, 10, or 100 mV/A). For example:
20 mV per division = 20 A per division
1 mV/A
Setups using the Current Probe and a ScopeMeter are shown in Figure 3.

Measurement Considerations
13
Measurement Considerations
Observe the following guidelines for positioning the Current Probe jaws:
• Carefully move the probe to center the conductor inside the jaws.
• Make sure the probe is perpendicular to the conductor.
• If possible, avoid measurements close to other current-carrying
conductors.
On the Current Probe, the 1 mV/A range offers the best accuracy and least
phase shift. When using the 1 mV/A probe range, use the “volts per division”
adjustment on your oscilloscope for best display results.
Note
Although it is possible to change the range on the current probe
without removing the probe from the current carrying conductor,
remember not to exceed the permissible peak ratings. The peak
ratings by range are: 20 A peak @ 100 mV/A, 200 A peak @ 10 mV/A
and 2000 A peak @ 1 mV/A.
Maintenance
Before each use, assure continued safety of the probe by inspecting it for
cracks or missing portions of the insulating cover and for loose or weakened
components. Pay particular attention to the insulation surrounding the probe
jaws. Any probe that fails this inspection should be made inoperative by taping
the probe shut to prevent unintended operation.
Cleaning and Storage
Periodically wipe the case with a damp cloth and detergent; do not use
abrasives or solvents. Open the jaws and wipe the magnetic pole pieces with a
lightly oiled cloth. Do not allow rust or corrosion to form on the magnetic core
ends.
